ezjs

A light Javascript (ES5 version) runtime library , you can use Javascript as DSL in your project. Whole design is inspired from https://mujs.com/, including including a simple bytecode virtual machine. You can added a extenstion hook type via Rust's generic features, and this hook type play key role in your DSL enviroment.

All implementation including tokenlizer, AST builder, compiler, optimizer(TODO), and VM executer is simple and easy to debug, so I called this library ezjs.

An completed example is a repl ( src/bin/repl.rs), which including a hookable extention struct.

No runtime deps
